Gemcitabine-induced radiation recall (GIRR) is a phenomenon wherein the administration of gemcitabine induces an inflammatory reaction within an area of prior radiation. We present the case of a 39-year-old female patient with metastatic breast cancer who experienced GIRR myositis 3 months following postoperative radiotherapy, with additional potential paraspinal myositis following ablative radiotherapy to the thoracic spine. A review of previously published cases of GIRR myositis was performed. The case and literature review describe the clinical course and presentation of GIRR, and highlight the importance of including radiation recall as part of a differential diagnosis when a patient undergoing chemotherapy experiences an inflammatory reaction at a prior site of radiation...

PURPOSE: Radiotherapy is a common adjuvant treatment of breast cancer. Acute radiation-induced dermatitis is a frequent side effect. We hypothesized whether it is possible to capture the increase of local temperature as a surrogate of the inflammatory state induced by radiotherapy. We designed a prospective, observational, single-centre study to acquire data on temperature rise in the treated breast during the course of radiotherapy, establish a possible association with the occurrence of dermatitis and investigate the predictive value of temperature increase in future occurrences of radiation-induced dermatitis...

PURPOSE: The 2014 Society of Surgical Oncology-American Society for Radiation Oncology consensus suggested "no ink on tumor" is a sufficient surgical margin for invasive breast cancer treated with breast-conserving surgery (BCS). Whether close margins <2 mm are associated with inferior outcomes remains controversial. This study evaluated 10-year outcomes by margin status in a population-based cohort treated with BCS and adjuvant radiation therapy (RT). METHODS AND MATERIALS: The subjects were 10,863 women with invasive cancer categorized as pT1 to T3, any N, and M0 referred from 2001 to 2011, an era in which the institutional policy was to re-excise close or positive margins, except in select cases...

PURPOSE: To develop and evaluate a new automatic classification algorithm able to identify voxels containing skin, vasculature, adipose and fibroglandular tissue in dedicated breast CT images. METHODS: The proposed algorithm combines intensity and region-based segmentation methods with energy minimizing splines and unsupervised data mining approaches for classifying and segmenting the different tissue types. Breast skin segmentation is achieved by a region growing method which uses constraints from the previously extracted skin centerline to add robustness to the model and to reduce the false positive rate...

Various types of vaccines have been proposed as approaches for prevention or delay of the onset of cancer by boosting the endogenous immune system. We previously developed a senescent-cell-based vaccine, induced by radiation and veliparib, as a preventive and therapeutic tool against triple-negative breast cancer. However, the PD-1/PD-L1 pathway was found to play an important role in vaccine failure. Hence, we further developed sPD1-expressing senescent cells to overcome PD-L1/PD1-mediated immune suppression while vaccinating to promote dendritic cells (DCs) maturity, thereby amplifying T cell activation...

Medical oncology is in need of a mathematical modeling toolkit that can leverage clinically-available measurements to optimize treatment selection and schedules for patients. Just as the therapeutic choice has been optimized to match tumor genetics, the delivery of those therapeutics should be optimized based on patient-specific pharmacokinetic/pharmacodynamic properties. Under the current approach to treatment response planning and assessment, there does not exist an efficient method to consolidate biomarker changes into a holistic understanding of treatment response...

INTRODUCTION: Secondary lymphedema is the most frequent long-term complication of axillary lymphadenectomy. It can result in complication as erysipelas, warts, Papilloma Cutis Lymphostatica (PCL), or angiosarcomas. Moreover, in women affected by breast cancer an accurate differential diagnosis among these conditions or complication related to radiation dermatitis or cutaneous metastasis is essential. PRESENTATION OF CASE: We report the case of a 60-year-old postmenopausal Caucasian woman affected by secondary lymphedema following complete mastectomy for breast cancer...

Triple negative breast cancer is an aggressive disease that accounts for at least 15% of breast cancer diagnoses, and a disproportionately high percentage of breast cancer related morbidity. Intensive research efforts are focused on the development of more efficacious treatments for this disease, for which therapeutic options remain limited. The high incidence of mutations in key DNA repair pathways in triple negative breast cancer results in increased sensitivity to DNA damaging agents, such as platinum-based chemotherapies...

BACKGROUND:  Postmastectomy radiation therapy (PMRT) is a widely accepted treatment for locally advanced breast cancer. Some patients require additional boost radiation to the internal mammary nodes as the part of regional nodal irradiation (RNI). Delayed breast reconstruction with an autologous free flap using the internal mammary vessels for microvascular flap anastomosis is a common practice for these patients. The aim of our study was to evaluate the effect of RNI on autologous microvascular breast reconstruction...

BACKGROUND: High-volume single-institution studies support the oncologic safety of nipple sparing mastectomy (NSM). Concerns remain regarding the increased potential for complications, recurrence, and delays to subsequent adjuvant therapy. A national database was used to examine treatment and outcomes for NSM patients. METHODS: Women undergoing unilateral NSM or skin sparing mastectomy (SSM) for stage 0-4 breast cancer from 2004 to 2013 were identified from the National Cancer Database...

Historically, heart dose from left-sided breast radiotherapy has been associated with a risk of cardiac injury. Data suggests that there is not a threshold for the deleterious effects from radiation on the heart. Over the past several years, advances in radiation delivery techniques have reduced cardiac morbidity due to treatment. Deep inspiration breath hold (DIBH) is a technique that takes advantage of a more favorable position of the heart during inspiration to minimize heart doses over a course of radiation therapy...

Efficient magnetic reactive oxygen species (ROS) formation enhancing agents after X-ray treatment are realized by functionalizing superparamagnetic magnetite (Fe3 O4 ) and Co-ferrite (CoFe2 O4 ) nanoparticles with self-assembled monolayers (SAMs). The Fe3 O4 and CoFe2 O4 nanoparticles are synthesized using Massart's coprecipitation technique. Successful surface modification with the SAM forming compounds 1-methyl-3-(dodecylphosphonic acid) imidazolium bromide, or (2-{2-[2-hydroxy-ethoxy]-ethoxy}-ethyl phosphonic acid provides biocompatibility and long-term stability of the Fe3 O4 and CoFe2 O4 nanoparticles in cell media...

Lung cancer is the leading cause of cancer death and second most common cancer among both men and women, but most of them are detected when patients become symptomatic and in late-stage. Chest radiography (CR) is a basic technique for the investigation of lung cancer and has the benefit of convenience and low radiation dose, but detection of malignancy is often difficult. The introduction of computed tomography (CT) for screening has increased the proportion of lung cancer detected but with higher exposure dose and higher costs...

Breast cancer is the second leading cause of cancer death among women worldwide and besides life-style, age and genetic risk factors, exposure to ionising radiation is known to increase the risk for breast cancer. Further, DNA copy number alterations (CNAs), which can result from radiation-induced double-strand breaks, are frequently occurring in breast cancer cells. We set out to identify a signature of CNAs discriminating breast cancers from radiation-exposed and non-exposed female patients. We analysed resected breast cancer tissues from 68 exposed female Chernobyl clean-up workers and evacuees and 68 matched non-exposed control patients for CNAs by array comparative genomic hybridisation analysis (aCGH)...

BACKGROUND: Patients with breast cancer who have a pathologic complete response (pCR) to neoadjuvant chemotherapy (NACT) have improved survival. We hypothesize that once pCR has been achieved, there is no difference in subsequent postsurgical recurrence-free survival (RFS), whichever NACT regimen is used. METHODS: Data from patients with breast cancer who achieved pCR after NACT between 1996 and 2011 were reviewed. RFS was estimated by the Kaplan-Meier method, and differences between groups were assessed using log-rank testing...

Introduction: Breast cancer care imposes a significant financial burden to U.S. healthcare systems. Health services factors, such as insurance benefit type and care source, may impact costs to the health system. Beneficiaries in the U.S. Military Health System (MHS) have universal healthcare coverage and access to a network of military facilities (direct care) and private practices (purchased care). This study aims to quantify and compare breast cancer care costs to the MHS by insurance benefit type and care source...
